HAY-PRESS.

SPECIFICATION forming part of Letters Patent No. 496,457, dated May 2,1893. Application filed November 19. 1892. Serial No. 452,531. (Nomodel.)

To all whom it may concern:

Be'itknown that we, J osEPH F. THOMPSON, RICHARD L. MURPHREE, andWILLIAM D. HARRISON, citizens of the United States, residing at Salado,in the county of Bell and State of Texas, have invented a new and usefulHay-Press, of which the following is a specification.

Our invention relates to improvements in hay-presses; the objects inview being to provide a press of cheap and simple construction, and soarranged as to alternately feed the hay 'into the chamber, and press thesame, the

two mechanisms being operated from the same source; to provide forincrease of power, and

for regulating the tension or mouth of the 1press at the point of exitof the completed Other objects and advantages of the invention willappear in the following description, and the novel features thereof willbe particularly pointed out in the claim.

Referring to the drawings:Figure 1 is a perspective view of a pressembodying our invention. Fig. 2 is a transverse -sectiou. Fig. 3 is alongitudinal-section.

Like numerals of reference indicate like parts in all the figures of thedrawings.

The baling-chamber comprises a pair of ordinary base-sills 1, and a pairof upper topsills 2, the pairs of sills being connected, as is usual, bythe uprights 3, also arranged in pairs, and the whole structure boundsecurely together by transverse tie-bolts 4. The basesills 1 extend invfront of the press, as shown, and are supported upon transverse sills 5,which at one side of thepress support a platform 6. The baling-chamberis further provided with a bottom 7 and with a top 8, said bottom andtop having their rear ends extending in rear of the delivery-mouth ofthe press. A caster 9, may if. desired be swiveled to the under side andrear end of the bottom of the press. Between the top and bottom of thepress the uprights have secured thereto the side-walls 10,- and theseside-walls have their rear ends disconnected from the rear uprights andare borne upon by crankedscrews 11, so that they may be squeezedtogether and thus reduce the width of the mouth of the press. Theside-walls are-slotted in the usual manner so as to receive thebinding-wires, whereby the bale may be bound previous to its deliveryfrom thepress. This completes the construction of the balingchamber,with the exception of a feed-mouth or opening 12, which is formed in oneof the side walls thereof near the front end of the press, and a plunger13 which is mounted for movement within the chamber and over the bottomthereof, which in addition to being extended in rear'of the press alsoextendsin front of the same.

A frame or standard 14 rises from the platform of the press at one sidethereof, and is disposed longitudinally with relation to thebaling-chamber. This frame has an upper bearing 15, which is in verticalalignment with a similarbearing 16 in the platform, and in thesehearings there is journaled a vertical power-shaft 17, to which isconnected above the frame 14, a sweep-arm to which the horses foroperating the press may be hitched in the usual manner. Within the frameor-between the bearings of the vertical shaft there is mounted on thelatter a large beveled-gear 18.

In a series of three standards 19,1ocated upon the plat-form 6, in frontof the balingchamber, and to one side of the frame 14, there isjournaled a transverse horizontal powershaft 20,'the outer end of whichhas secured thereto a large beveled gear 21, which is engaged and drivenby the gear 18 of the vertical power-shaft. Between those bearings 19that occur in front of the baling-chamber, the shaft 20 is provided witha cranked-portion 22, and a link or pitman 23, is loosely connected tosaid cranked-portion at the opposite end to the plunger 13. To that endof the shaft 10 farthest from the frame 14 the same is provided with asmall gear-wheel 24, and the same engages with and drives acorresponding beveled gear-wheel 25, which is located on the front endof a shaft 26, journaled in a vertical standard 27 rising from the outerbase-sill 1 and at that side of the baling-chamber provided with theopening. The rear end of this shaft is provided with a crank-arm 28.

By means of hinges 29 secured to the op- I00 posit-e sides of thefeechopening in the balingchamber there is secured a way or platform 30,and in the same there is mounted areciprocating-plunger 31, having anenlarged head 32, adapted to pass within the feed-opening of thebaling-chamber. Flanges 34, rise from the opposite sides of the guide30, and receive the inner end of a projection 33 that extends inwardlyfrom a standard 4:1,the latter maintaining the plunger in positionwithin the guides. An arm 35 extends from the guides 30, and a lever 36,is fulcrumed between its ends upon the outer end of the arm. A link 37,loosely connects one end of the lever with the outer end of thereciprocatingplunger, and a connecting-rod 38, connects the opposite endof the lever with the crankarm 28 of the shaft 26.

If desired, the ends of the front transversebeam 5 may be reduced toform journals 39, and the same are provided with wheels 40, which inconnection with the caster-wheel at the rear end of the baling-chamberwill permit of atransportation of the press. In such instance, also, itis preferable to hinge the guide 30 to the sides of the balingchamber,in that the same may then be swung up and the press be enabled to passthrough smaller openings in buildings than would otherwise be the case.If preferred, however, the guide need not be hingedly connected to theside of the balingchamber, and the wheels and caster may be omitted.This completes the construction of our invention, and the operation ofthe same is as follows: The horses are started, and through the mediumof the sweep motion is imparted to the verticalshaft, from which motionis imparted to the horizontal power-shaft 20, through the means of theintermediate gears. The shaft 20 by reason of its crankedportion,throughthe medium of the pitmanrod, reciprocates the plunger into and out ofthe balingchamberin a manner as will be obvious. The rotations of theshaft 20 are imparted to the shaft 26 and its cranked end through themedium of the connecting-rod 0s cillates the lever 36, thusreciprocating the plunger 31 which is the feed-plunger. Hay isintroduced in the front of the feed-plunger between the flanges 3i, andas the feed-plunger reciprocates the hay thus deposited is forced intothe baling-ohamber in advance of the plunger 13; in other words, theplungers operate alternately, and as the main plunger 13 is withdrawnthe supplemental-plunger is advanced and a deposit of hay pushed intothe baling-chamber, and being guided by the main plunger is advancedthereby and packed against the preceding bale. By regulating the widthof the exit mouth of the balingchamber it will be obvious that theresistance offered to the advancing bale may be increased or diminished,and in this manner a requisite density may be given to the bale.

From the foregoing description, in connection with the accompanyingdrawings,it will be seen that we have provided a machine of greatsimplicity, the same being adapted to rapidly form bales of requireddensity, and have provided a means for automatically feeding thematerial to be baled into the chamber.

Having described our invention, what we claim is In a baling-press, thecombination with the baling-chamber having the opening at one side, theplatform having ways extending from the opening, the plunger providedwith a head mounted for reciprocation in the ways, and a lever fulcrumedand pivotally supported at the rear end of the platform and connected tothe plunger, of bearings locatedin front of the baling-chamber, acrank-shaft journaled in the bearings, a pitman loosely connected to thecrank-shaft, a plunger mounted in the baling-chamber and connected, tothe opposite end of the pitman, an intermediate bearing, an intermediateshaft,gears on the adjacent ends of the crank and intermediate shafts,means for operating the crank-shaft, a crank on the rear end of theintermediate shaft,

and a con necting-rod between said crank and the free end of the lever,substantially as specified.

In testimony that We claim the foregoing as our own we have heretoaffixed our signatures in the presence of two witnesses.
